Umbrella locking device



May 8, 1934; w. STABY UMBRELLA LOCKING DEVICE- Filed Aug. 51, 1933Patented May 8, 1934 UNITED STATES UMBRELLA LOCKING DEVICE WilhelmStaby, Munich, Germany Application August 31, 1933, Serial No. 687,666In Germany September 21, 1932 2 Claims. (Cl, 135-44) Umbrella lockingdevices are known, in which a sleeve-shaped catch acted upon by a springis loosely mounted on the slide sleeve holding the inner ends of thestays, and the ends of the ribs 5 carry hooks which can engage the catchwhen pressed against the same after the closing of the umbrella. In thecase of these known umbrella locking devices the catch must be pulledback slightly against the action of its spring when opening theumbrella, and the ribs must then be slightly spread by hand so that,when the slide sleeve and catch sleeve are subsequently shifted, thehooks do not again engage in the catch sleeve and prevent the opening ofthe umbrella. This invention relates to an improvement of this umbrellalocking device and attains the novel effect that, by shifting the slidesleeve and the catch sleeve against the action of the spring, the ribsare released by the catch and immediately thereafter the spreading ofthe ribs and the opening of the umbrella takes place in a singleoperation. Moreover, means are provided on the ribs for preventing theribs from turning after the closing of the umbrella and during thepressing of the hooks of the ribs into the catch. An embodiment of theinvention is illustrated by way of example in the accompanying drawingin which:

Fig. l is a longitudinal section through the locking device.

Fig. 2 is a cross-section on line IIII of Fig. l. A sleeve 2 is slidablymounted on an umbrella stick 1, and the inner ends of the stays 4 of theumbrella frame are pivotally connected to a rim 3 on the inner end ofthe sleeve 2, whereas the outer ends of these stays are connected to theribs 6 by hinges 5. A handle 8 and a sleeveshaped catch 9 are slidablymounted on the sleeve 2, and a pressure spring 10 is fitted between thecatch 9 and the rim 3 of the sleeve 2, so that this spring presses thecatch 9 against the handle 8 and this latter against a flange 11 on theouter end of the sleeve 2. The sleeveshaped catch 9 has on its endbearing against the spring 10 a U-shaped annular flange 12 the open sideof which is directed towards the umbrella handle. Each rib 6 hasadjacent its outer end a hook 7 extending radially towards the1ongitudinal axis of the umbrella stick and open towards the point ofthe umbrella. This hook is provided with an inclined inner edge 13, sothat, when the umbrella is closed, this edge bears against the loweredge of the flange 12 of the catch and, when the hooks are pressedagainst the catch, forces the catch under the action of its spring 10 inthe direction towards the umbrella point, so that the hooks 7 springaway from the handle and. engage behind the edge of the U-shaped flange12 of the catch. In order to prevent the ribs from twisting andpreventing an engagement of the hooks, a small strap 14 is provided oneach rib adjacent the hooks and projecting from both sides of the rib sothat its projecting ends form an arc the curvature of which is adaptedto the outer circumference of the U-flange 12 of the catch. These straps14 bear against the circumference of the U-flange of the catch andprevent the ribs from turning, they are preferably made of resilientmaterial.

In order to open the umbrella, the handle 8 is pushed towards theumbrella point. The handle 8 first shifts the catch 9, which presses onthe spring 10 and this latter acts against the rim 3 of the slide sleeve2. Owing to the yielding of the spring 10 the edge of the U-fiange onthe 75 catch 9 is disengaged from the hooks '7 and the spreading of theribs 6 and the opening of the umbrella can take place in a singleoperation.

I claim:-

1. An umbrella locking device, comprising in combination with the stays,the ribs of the frame and the handle and stick of the umbrella, hooks,one on the outer end of each of said ribs open towards the point of saidstick, a slide sleeve loosely mounted on said stick, a sleeve-shapedcatch loosely mounted on said slide sleeve, and a U-shaped flange opentowards said handle and adapted to engage said hooks, a rim on the innerend of said slide sleeve, and hingedly connected to said stays, a flangeon the outer end of said slide sleeve, a handle loosely mounted on saidslide sleeve between said outer flange and said catch, and a spring onsaid slide sleeve between said catch and said inner rim.

2. An umbrella locking device, comprising in combination with the stays,the ribs of the frame and the handle and stick of the umbrella, hooks,one on the outer end of each of said ribs open towards the point of saidstick, a slide sleeve loosely mounted on said stick, a sleeve-shapedcatch loosely mounted on said slide sleeve, and a U-shaped flange opentowards said handle and adapted to engage said hooks, straps, one oneach of said ribs adjacent said hook and having laterally projectingends adapted to bear against said U-shaped flange to prevent a twistingof said ribs, a rim on the inner end of said slide sleeve, and hingedlyconnected to said stays, a flange on the outer end of said slide sleeve,a handle loosely mounted on said slide sleeve between said outer flangeand said catch, and a spring on said slide sleeve between said catch andsaid inner rim.

WILHELIVI STABY.
